She claims she woke up to find White standing over her with a cord in his hand and that he was going to choke her.

'We were fighting and he had a cord in his hand and was going to choke me. I got a cord and choked him with it,' Ray said.

Ray cut up White's body and tried to burn it before fleeing to Redding, California where she was arrested on November 13.

Her boyfriend's remains were found at his residence on November 12 after police received a tip that he may have been dead.

Ray said: 'We were fighting and he had a cord in his hand and was going to choke me. I got a cord and choked him with it.' She then cut up his body and tried to burn it before fleeing to Redding, California where she was later arrested

An autopsy confirmed that White died of 'homicidal violence'.

Prosecutors allege that the 26-year-old tried to hide his remains and avoid prosecution.

The victim's parents told the Herald and News that the pair had been living together for roughly three months before White's death.

Ray will be sentenced on August 14 and she faces between 25 years and life in prison.
